We're up to re-use old phones like "Club Telephones" or "FETAP" with VoIP, we're also devoloping on a LIDAR-system (light detection and ranging). Old equipment with new technique. Just like "Bohnen in die Ohr'n" from singer Gus Backus: Old song recycled into 8-bit, metal and rock versions at Easterhegg 2017.
